Answer:

3.14%

Explanation:

FV = PV(1+r/100)^n

FV= $36,420, PV= $31,208, r=? n= 5

36420 = 31208 * (1+r/100)^5

We divide both side by "31,208^5" to make  r in (1+r/100)  subject of formula

(36420/31208)^(1/5) = (1+r/100)

(1+r/100) = (36420/31208)^(1/5)  

(1+r/100)=1.0314

r=1.0314-1

r=0.0314

r=3.14%

The conclusion is that 3.14% is the annual increase in the selling price over this period of 5 years
